drivers/base: add bus for System-on-Chip devices
Traditionally, any System-on-Chip based platform creates a flat list
of platform_devices directly under /sys/devices/platform.
In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function. All devices that are on the same
chip should then be registered as child devices of the soc device.
The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.
